Endodontics is an area of dentistry which deals with the health of the pulp of a tooth and its surrounding structures. The treatment is also known as root canal treatment. 

Usually the treatment is required if the pulp tissue becomes infected or irreversibly inflamed, requiring an intervention. 

The procedure may involve one–visit or multiple–visit depending on the case.

Endodontics can be classified as:

• Vital pulp therapy (indirect pulp therapy, direct pulp capping, pulpotomy, regenerative pulp therapy)
• Nonsurgical root canal treatment
• Nonsurgical root canal retreatment
• Surgical retreatment
